John Ramsbottom
John Ramsbottom (1814–1897) was a British locomotive engineer who served as Chief Mechanical Engineer of the London and North Western Railway from 1862 until 1871, and who is remembered as much for a series of transformative engineering inventions — particularly the water trough, the Ramsbottom safety valve, and the split piston ring — as for any individual locomotive design, though his DX Goods 0-6-0 of 1858 was built in larger numbers than any other pre-Grouping British locomotive class.
Born at Todmorden, Yorkshire on 11 September 1814, Ramsbottom was apprenticed at Sharp, Roberts and Co. of Manchester and became Locomotive Superintendent of the Manchester and Birmingham Railway at Longsight in 1842, transferring at the LNWR's formation in 1846 to the Northern Division at Crewe. He succeeded Francis Trevithick as overall Locomotive Superintendent of the LNWR's Northern Division in 1857 and then of the whole railway in 1862.
The water trough, first installed at Mochdre on the Chester and Holyhead line in 1860, was Ramsbottom's most far-reaching invention: by allowing locomotives fitted with a scoop to pick up water at speed from a trough between the rails, it made possible non-stop runs over distances previously requiring intermediate water stops, transforming the economics and scheduling of long-distance express services. The Ramsbottom safety valve, which replaced the earlier lever-and-balance types with a more reliable spring-loaded design, and the split piston ring that reduced steam leakage past the piston were equally practical and widely adopted. His 943 DX Goods 0-6-0s formed the backbone of LNWR freight working for decades.
Ramsbottom retired in 1871 in poor health and was succeeded by Francis Webb. He continued in engineering consultation for the LNWR and died at Alderley Edge, Cheshire on 20 May 1897.
Biography
John Ramsbottom (1814–1897) was a British locomotive engineer who served as Locomotive Superintendent of the London and North Western Railway from 1862 until 1871. He is now perhaps better remembered for a string of pivotal inventions, the displacement lubricator, the Ramsbottom safety valve, the split piston ring and (most famously) the water trough, than for any individual locomotive class, though his DX Goods 0-6-0 of 1858 was built in greater numbers (943) than any pre-Grouping British class.
Ramsbottom was born at Todmorden, Yorkshire on 11 September 1814 and apprenticed to Sharp, Roberts & Co. of Manchester. He was Locomotive Superintendent of the Manchester & Birmingham Railway at Longsight from 1842, transferring at the LNWR's formation in 1846 to take charge of the Northern Division at Crewe. In 1857 he succeeded John Trevithick (son of Richard) as overall Locomotive Superintendent of the LNWR's Northern Division and from 1862, on the death of Francis Trevithick, of the whole LNWR.
The water trough, first installed at Mochdre on the Chester & Holyhead in 1860, allowed locomotives fitted with a scoop to take on water at speed and so transformed the operation of long-distance non-stop services. The displacement lubricator and the four-feed Ramsbottom safety valve were widely adopted across the British network. His DX Goods, much rebuilt, lasted in LMS service until 1930.
Ramsbottom retired in 1871 in poor health and was succeeded by Francis Webb. He continued as a consulting engineer to the LNWR for many years and as a member of the Board. He died at Alderley Edge, Cheshire on 20 May 1897.
